Need Help in Dbus

[Matthias Huber]

(Reposting from devel@, hoping that here is maybe one)

Hello List,

for my minimoko, i want to implement the battery status and network
status and therefore i want to listen on the dbus.

for not consuming too much resources, i'd like to do this in "pure c"
and with the lowlevel routines.

i found an example here: http://dbus.freedesktop.org/doc/dbus/dbus-example.c

in this example is a section "receive", which i want to use.

now i tried :

  // add a rule for which messages we want to see
   dbus_bus_add_match(conn,
"type='Event',interface='org.freesmartphone.Device.Input'", &err); //
see signals from the given interface
   dbus_connection_flush(conn);
   if (dbus_error_is_set(&err)) {
      fprintf(stderr, "Match Error (%s)\n", err.message);
      exit(1);
   }
   printf("Match rule sent\n");

but i only got:

Match rule sent
Got Signal with value :1.6
Got Signal with value org.freesmartphone.ousaged


I am trying any other combination of bus and interface / path, always 
the same.

when i try another call, i get

root at om-gta02 ~ # dbus-test
Listening for signals

process 2609: type array 97 not a basic type
   D-Bus not built with -rdynamic so unable to print a backtrace
Aborted


(this was a call to the dbus itself for listing its busses),
works with mdbus well, but not in my program.

What am i doing wrong ?
